Duckworth is challenging incumbent Rep. Joe Walsh, a first-term Republican who represents the state’s 8th Congressional District. After being reconfigured in a redistricting process, the district now leans more Democratic than when Walsh last ran in 2010.

But the other Walsh–the one who wooed America with his 1978 solo hit “Life’s Been Good”–encouraged voters to turn out for Duckworth this November in his home state of Illinois.

“I’m the real Joe Walsh and I’m proud to back a real American success story – Tammy Duckworth,” Walsh said in a statement. “Tammy’s story, her service to our nation and her continued commitment to working families (like the one I come from!) have convinced me that she’s the right choice for Congress.”

The rocker will perform at a concert for Duckworth in July.

This marks Duckworth’s second run for Congress. The Iraq war veteran made an unsuccessful House bid in 2006, prior to being tapped by President Barack Obama in 2009 to become the Assistant Secretary of Veterans Affairs.
